    {
      "q": "How do I calculate air freight volume?",
      "a": "Multiply packed length, width, and height, convert the result to cubic meters, then multiply by carton quantity."
    },
    {
      "q": "Is air freight priced by CBM?",
      "a": "Air quotes usually use chargeable weight, not CBM alone. CBM is converted to volume weight and compared with actual gross weight."
    },
    {
      "q": "What air freight divisor should I use?",
      "a": "Use 6000 cm3/kg for standard air freight unless your forwarder specifies a different divisor. Use 5000 for many express courier services."
    },
    {
      "q": "What dimensions should I enter?",
      "a": "Use the outer packed carton or pallet dimensions as tendered to the carrier, including bulge, wrap, and pallet height."
    },
    {
      "q": "What does 1 CBM mean for air freight?",
      "a": "At a 6000 divisor, 1 CBM converts to about 166.7 kg of volume weight. At a 5000 divisor, 1 CBM converts to 200 kg."
    },
    {
      "q": "Can I use this for Amazon FBA air shipments?",
      "a": "Yes, use it for planning carton volume before quoting FBA air freight, then confirm final chargeable weight with your forwarder."
